DEVICE FOR ATTACHING COLTERS TO PLOWS.

SPECIFIC'ATION forming part of Letters Patent N0. 367,697, dated August2, 1887.

Application filed May 5, 1887. Serial No. 237,286. (No model.)

To aZZ whom it may concern.-

Be it known that I, NICHOLAS BURCH, a citizen of the United States,residing at Toledo, in the county of Lucas and State of Ohio, haveinvented certain new and useful Improvements in a Device for AttachingGolters to Flows; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form part of this specification.

My invention relates to a device for attaching colters to plows, and hasfor its object to provide means by which the strain from the coltershall be transferred from the beam or standard to a supplemental cap;also, to so arrange the parts that the colter can be given any desiredinclination by simply moving the locking-cap and without removing theparts from the beam.

Myinvention consistsin minor details of construction, that will beparticularly described, and pointed out in the claims.

Figure 1 is a perspective view of a plow provided with my improvements,showing in full and dotted lines different adjustments of inclinationsto the colter. Fig. 2 is an isometrical perspective of the outer face ofthe flanged portion of the plow-standard, the lower portion of thestandard being omit-ted. Fig. 3 is a plan view of the inner face of thelockingcap.

Like letters of reference indicate like parts throughout the views.

A represents the plow, having beam B.

C is an upturned flange, preferably formed integral with theplow-standard and provided with bolt'holes F and G, also with lug L atits lower and a lug, M, at its upper side. Lug L is formed withserrations L, for a purpose hereinafter stated. 7

D represents a pivoted locking-pl ate having abolt-hole, O, and anelongated curved slot, H, registering with holes F and G, respectively,upon the flanged plate 0. Cap D is provided with lugs N N upon its innerside, also a lug,

K, having a V-shaped tooth, K, upon its danger of breakage to the beamor flanged plate is obviated.

The operation is as follows: Cap D is pivotally attached to the flangedplate 0 by bolts passing through perforations F and O G and slot H.Thesebolts may extend through the beam or simply through the two plates.In the latter case the heads should be countersunk into the rear side ofthe flanged plate 0. The colter is now placed in position between plates0 and D. If the greatest inclination to the colter is desired, tooth Kis placed in 'thelowest scrration of the flanged plate, the bolts arerun firmly to place, and the plow is ready for use. To change theinclination of the colter, it is only necessary to unscrew the nuts fromthe bolts a sufficient distance to allow the cap to be moved upon thepivot, placing tooth L in any desired serration, and tighten the bolts,as previously described.

By the arrangement of K and M L and M the back-pressure of the colterupon lugs K and L results in a forward pressure upon lugs M and M,thereby greatly equalizing the strain upon flanged plate 0.

My device is durable, inexpensive, and readily attached. v

Having described my invention, what I claim, and desire to secure byLetters Patent,

1. In a device for attaching colters to plows, a pivoted locking-capprovided with bearings for the colter, a flanged plate having lugsadapted to receive the strain of the lockingplate upon the inner side ofone lug and the outer side of the other lug, as and for the purpose setforth.

2. A flanged plate having a smootlrfaccd upper lug and a serrated lowerlug, a pivoted loekingoap having bearings for the eolter, one Intestimony that I claim the foregoing as of the bearings having a V-shaped tooth my own I hereby affix my signature in presadapted to engagewith any desired serration once of two Witnesses. upon the inner face ofthe lower lug upon the 5 flange-plate, and an upper bearing fitting uponVitnesses:

the outer face of the upper lug, as and for the LUTHER G. RAYMER,purpose set forth. 1, WILLIAM WEBSTER.

NICHOLAS BURCH.
